i have a Racing Beat Aluminum Main Pulley and it has 3 timing marks engraved on it i was able to figure the first one (from left to right) is tdc but i cant find any info on what degrees the other two marks are. any info would be helpfull

 

Is it the same size as the original or is it an underdrive?

 

underdrive

 

Best bet is to call them.

 

^ That would be the smart thing to do. :-)
